88611 Teharonhiawako is a trans-Neptunian object and a member of the Kuiper belt, measuring 156–196 km in diameter. It is a binary object, with a large companion named Sawiskera (pronounced [zaɰískɛɺa] in Mohawk,[5] formally designed (88611) Teharonhiawako I Sawiskera), which at 108–136 km in diameter is about two-thirds the size of its primary.[2]

Teharonhiawako was discovered on August 20, 2001, by the Deep Ecliptic Survey, and Sawiskera was identified a month later. The primary is named after Teharonhiawako, a god of maize in the Iroquois creation myth, while the secondary is named after his evil twin brother Sawiskera. The objects were named in 2007.[2]
